Answer:
x = -1/3
Step-by-step explanation:
I think you mean 25x+5=10x
F(x)=3x-2
f(-6)=3(-6)-2
=-18-2
=-20
4y⁴ - 8y³ - (5y³ + 6y + 3y⁴)
= 4y⁴ - 8y³ - 5y³ - 6y - 3y⁴
= (4y⁴ - 3y⁴) + (- 8y³ - 5y³) - 6y
= y⁴ - 13y³ - 6y
Answer: y⁴ - 13y³ - 6y
we are given that out of 100 light bulbs, 7 of them were defective. We can assume that out of every 100 lightbulbs, 7 of them will be defective.
we can write this as a ratio of defective lightbulbs to total
7:100
we want to see how many defective there are when we have 3000 bulbs, to do this we can multiply both numbers by 30
7 * 30 = 210
100 * 30 = 3,000
our new ratio is now
210:3,000
so we are now able to say that in a lot of 3,000 lightbulbs, there would be 210 defective bulbs.
hope this helped!
